Slate roofing materials

Compared with traditional roofing materials,slate roofing materials has its unique advantages, such as to reduce weight, increase strength and change into complex shapes and easy coloring.British PlastechTT RTM process developed glass fiber reinforced plastic roofing sheet, to replace the original 56 × 15cm, 30 × 15cm stone plate, the weight can be reduced by 92%, and can greatly reduce the construction and installation time. Fiberglass roofing sheet in horizontal and vertical directions, are designed to overlap in order to prevent leakage of rainwater. And, thanks to a new fixed, so the outer surface is not observed signs of joint. Roofing sheet using a single color, and has a certain resistance to weathering performance.
The RTM fabrication sheet is the first glass fiber into the female mold, low pressure injection of thermosetting resin (pressure of about 100 ~ 400kPa), and then curing. The Company believes that the RTM investment initially lower aluminum tool investment and automation investment, are relatively cheap, but it can produce high-end roofing materials, and can long-term, stable, continuous production.In addition, the size and shape is very close to the finished product after the release of the RTM products processing is very simple. To ensure the FRP roofing materials to achieve the desired performance, the choice of reinforcements and the matrix resin, it is very important.The believes that the E-glass continuous fiber mat is an ideal reinforcement materials, to ensure that the glass fiber reinforced plastic roofing material with a certain volume fraction and good mechanical properties.
